You Can Touch, but You Can't Look: Interacting with In-Vehicle Systems

Summary:
This paper wanted to test different ways of interacting with a car radio. They used three types of input: buttons like in our cars currently, a touch screen, and gesture based. They then tested the driver for how long they took to finish the task, how many mistakes they made, as well as how many driving mistakes they made while attempting the task. Tactile input (our current way) caused the driver to make by far the most driving mistakes while at the same time taking the longest to complete the task. Touch based allowed the user to complete the task the fastest, but they had to look away from the road more often than gesture based to do it. Completion time for gesture based was almost as long as tactile, but the driver did not have to look away from the road for long periods of time.

Discussion:
This report was interesting because it could make driving safer. Just like cell phones are dangerous while driving, looking at the radio is also dangerous since you aren't looking at the road. It was interesting that touch causes so fewer errors than tactile since both require you to look away from the road. I would like to see some kind of combination of touch and gesture to see what results happen. They could use the touch for more advanced commands while using gesture for simple commands.
